I have downloaded the software and reinstalled it on multiple occasions. I have no issues until I get to the kriging stage when it just aborts saying what is attached in the photo! See attached JPG. I have wateched You Tube tutorials and think that I am entering the data correctly. I have tried a 32 bit version also with no success. Any help would be appreciated as I have spent a day trying all different approaches with no success.
